Pain can be a symptom for many conditions and diseases, but what happens when it doesn’t have a definable cause? Fibromyalgia is a disorder that causes fatigue and a pattern of unexplained mild-to-intense pain throughout the body. The condition is six times more common in women than in men, though this female predominance seems to be much lower when newer diagnostic criteria are used.

The cause of the disorder is as yet unknown, and there is no cure. However, your doctor can help you manage your symptoms with lifestyle changes and medication.

“One way to think about fibromyalgia is that a person’s “pain thermostat” is set too low. For patients, this pain is real. It’s not just in their heads. But it can be much harder to treat that many other types of pain, says Joshua Bilsborrow, MD, a Yale Medicine rheumatologist.
